Direct endoscopic intratumoral injection of Onyx for the preoperative embolization of a recurrent juvenile nasal angiofibroma

Interv Neuroradiol. 2011 Dec;17(4):477-81. doi: 10.1177/159101991101700413. Epub 2011 Dec 16.

Abstract

Percutaneous injection of embolization material within head and neck tumors is being described as an alternative or adjunct to transarterial embolization. Access in these reports is by computed tomography (CT) guidance, which is cumbersome given the need to transport the patient from the CT scanner to angiography suite. We describe a case of direct percutaneous onyx embolization of juvenile nasal angiofibroma following endoscopic access in the angiography suite including self-sustained onyx combustion during surgical electrocautery.
